Definitions

  • This invention relates to a sealing member capable of stabilizing a movable element particularly, although not exclusively, a movable window pane of a motor vehicle, and its method of production.
  • Waistseal sealing members which comprise a resiliently flexible lip extending from a relatively rigid body which is attachable to a window surround of a motor vehicle door.
  • the lip is adapted to be in contact with a movable window pane when the window pane is partly or fully raised.
  • the window pane When the window pane is fully lowered, it can pass below the lip of the seal for part or all of the width of the glass and the lip flexes over the upper edge of the window pane.
  • metal, plastic, or rubber stabilizing elements have been attached by means of rivets, adhesive, tape or clips to the body of the seal in order that the stabilizing element is in contact with the window pane in all positions of its longitudinal (i.e. vertical) movement, thus restricting the lateral movement of the window pane.
  • certain disadvantages have been encountered with these known stabilizing elements. In this respect, it has been found to be very costly to incorporate a separate machine or employ a worker to attach the stabilizing elements after the waistseal has been produced. Additionally, the weight of the metal stabilizing elements has been found to be inconveniently large. Further disadvantages occur in the lead time and work in progress. Thus, in attaching a stabilizer the manufacturing lead time (the time from when component manufacture starts to packing) is prolonged, and the work in progress is increased due to the need to stock and handle an additional component.
  • a sealing member comprising: a resiliently flexible portion; a relatively rigid body portion having an upper portion and a lower portion; and an outwardly protruding stabilizer portion, wherein the resiliently flexible portion extends from the body portion, and wherein the stabilizer portion is integral with and formed from at least part of the body portion, and is positioned between the upper and lower portions of the body portion.
  • the resiliently flexible portion may be a lip portion or a bulb portion.
  • the lower portion preferably is an enlarged lower portion from which the stabilizer portion may be formed.
  • a low friction material such as flock is preferably positioned on the enlarged lower portion and may also be positioned on either or both of the stabilizer portion and the resiliently flexible portion.
  • the sealing member according to the second aspect of the present invention may further include a leg member, wherein the leg member and body member form a channel capable of receiving a flange member or the like on which the sealing member is to be positioned.
  • the resiliently flexible portion is formed of an elastomeric material and the body portion is conveniently formed of an elastomeric material surrounding at least a part of a reinforcing member.
  • the elastomeric material is preferably EPDM and, in a preferred embodiment, the reinforcing member is formed of steel or aluminium.
  • a method of forming a longitudinally extending stabilizing sealing member comprising: forming a sealing member having a resiliently flexible portion extending from a relatively rigid body portion, which body portion has an upper portion and a lower portion; forming a tongue in the body portion; and shaping the tongue to form an outwardly protruding stabilizer portion between the upper and lower portions of the body portion.
  • the flexible portion may be formed as a lip portion or as a bulb portion.
  • the tongue is preferably formed by making at least one cut, preferably two cuts, in the body portion and, in a preferred embodiment, the forming and shaping of the tongue are carried out by single device.
  • the tongue may be shaped by folding the cut portion, preferably twice.
  • the device may further cut the sealing member to the required length.
  • a sealing member shown generally at 2 comprising a body portion 4, a lip portion 6, and a leg portion 8.
  • the leg portion 8 and body portion 4 together form a channel 10 which is adapted to receive a flange portion of a vehicle window surround on which the sealing member 2 is to be positioned.
  • An aluminium reinforcing member 12 constitutes part of the body portion 4 and extends therefrom to form part of the leg portion 8.
  • EPDM rubber material 14 partially surrounds the reinforcing member 12 on the body portion 4 and leg portion 8.
  • the EPDM rubber material in the lower region of the body portion forms an enlarged portion 16.
  • the EPDM rubber material extends from the junction of the body portion 4 and leg portion 8 to form the lip portion 6 which is resiliently flexible.
  • Flocking material 18 is adhered to the enlarged portion 16 and to the resiliently flexible lip portion 6.
  • Mylar film 20 (which may alternatively be stainless steel) is present over part of the leg portion 8 in a region where it will be visible on the exterior of a vehicle.
  • the process for producing the known sealing member 2 is as follows.
  • An aluminium reinforcing member in the form of a flat sheet is rolled into the shape of the reinforcing member 12 with the mylar film 20 (or stainless steel) clinched.
  • the shaped reinforcing member 12 is passed through a rubber extrusion head where the EPDM rubber material 14 is applied.
  • the extrudate is then passed through an oven to vulcanize the EPDM material 14. Subsequently, the extrudate is treated in a chlorine tank in order to raise the surface energy of the EPDM material 14 and to allow good wet-out (intimate contact of adhesive and surface) and adhesion of adhesive.
  • Adhesive is then applied in the regions where flocking is required, and the flocking material 18 is applied electrostatically.
  • the flock adhesive is then cured in an oven and the product is cooled in a water tank.
  • the strip so produced is then cut to a length slightly larger than that which is to be required.
  • the over length part is then loaded into a transfer press which continuously moves up and down and in doing so gradually moves the part across a transfer press table in a series of defined lateral movements. At each of the defined movements, the part is automatically positioned in a press tool and the vertical movement ensures that a particular press operation is carried out at that point (for example the strip may be cut to length, or pierced, or notched).
  • the transfer press is capable of carrying out several operations without any operator involvement other than the original loading of the part.
  • the sealing member 2 is positioned on a window surround of a vehicle door such that the channel 10 receives a flange on the vehicle door.
  • the flocking material 18 of the lip portion 6 and enlarged lower portion 16 abut a movable window pane which may be raised or lowered.
  • the structure of the enlarged lower portion 16 is too weak to act as a stabilizer.
  • the flocking material provides a low friction surface for movement against the window pane. When the window pane is fully lowered, the resiliently flexible lip portion 6 flexes over the upper edge of the window pane, but the flocking material 18 of the lower portion 16 remains in contact with the window pane.
  • Figure 2 shows the sealing member of Figure 1 on which is attached a stabilizer portion 22.
  • the stabilizer portion 22 is formed of a metal base which carries an arcuate element formed of an elastomeric material on which is attached flocking material 24. Also provided on the stabilizer portion 22 is a hole 26 through which a rivet may be passed in order to attach the stabilizer portion 22 to the body portion 4 of the sealing member 2.
  • Figure 3 shows the sealing member of Figure 2 in use.
  • a glass window pane 28 is shown in its lowered position.
  • the stabilizer portion 22 abuts the window portion 28 in order to prevent lateral movement of the window pane 28 and therefore prevents vibration or rattling.
  • the enlarged lower portion may contact the window pane 28 but does not provide significant stabilization.
  • the stabilizer portion 22 in this respect exerts a small amount of lateral pressure thus holding the window pane 28 in position.
  • the lip portion 6 flexes over the upper edge of the window pane 28 but, as the window pane 28 is raised, the lip portion 6 flexes back but remains in contact with the glass window pane 28.
  • Figure 4A shows the sealing member 2 of Figure 1 which is to be shaped to form the sealing member of the present invention.
  • the sealing member 2 is prepared as described above in relation to Figure 1.
  • Figure 4B shows a diagrammatical face view of Figure 4A in which two cuts 30 and 32 are made in the body portion 4.
  • the cut portion is folded at folding points 34 and 36 in order that the enlarged lower portion 16 projects from a face of the body portion 4.
  • Each of the areas 38, 40, and 42 shown in Figure 5B are flocked.
  • the folded enlarged portion protruding from a face of the body portion 4 can act as a stabilizing portion 44 to prevent lateral movement of a window pane as described above.
  • the invention greatly simplifies the manufacturing process since the stabilizing portion 44 is created by punching and forming operations which can be carried out in the transfer press and do not require a separate attachment of the stabilizing portion.
